科学实验活动册系列答案There are many colors in nature. But do you know if a color has weight? I think you’ll say “no”. But I am afraid you are wrong. If you don’t believe, you may do a small experiment.
First, put two objects with the same weight into two boxes. Then cover the box. Third, wrap one box with a red piece of paper, the other with a white piece of paper. OK. Now hold the boxes with your hand one by one. It is certain that you will think the red one is a little heavier.
Why do you think so? A scientist found that different colors have different weight in a man’s mind. So he did man tests and at last he got the result. That is to say, every color has its own weight in our mind and their order is the same. The heaviest color is red, then blue, green, orange, yellow and white.
The scientist told us that colors also have smell. Can you smell the color? Of course not. Then why did the scientist say so? That is because every color stands for a kind of light with a certain wavelength. It reaches our brain through sense organs (感觉器官).
According to this discovery, scientists say that people accept the colors they like, and refuse the colors they hate. So your body and mind will be healthy by using the colors you like. Or you’ll be nervous or even get ill. For example, if you stay in a room with red windows, wallpapers and furniture for two hours, you’ll feel you have been there for four hours. But if the room is blue, you’ll feel you have been there for only an hour. Another example, if a person walks out of a red room and into a blue room, his temperature will fall. That means our body temperature will change with different colors.

Rosa Parks was an African-American woman who began the civil rights movement by refusing to give up her seat to a white person on a bus . She stood up for what she believed was right , and her courage inspired countless others to do the same.
Born in Alabama in 1913 , Mrs. Parks grew up on a farm just outside Montgomery in a town called Pine Level . She was home-schooled until she was 11. She later attended the Industrial School for Girls in Montgomery. She briefly attended the Alabama State Teachers College for Negroes , but had to drop out to take care of her mother and grandmother when they became ill.
Mrs. Parks married Raymond Parks in 1932 . He encouraged her to finish her education . This was very uncommon at that time , especially for a woman. Less than 7 percent of African-Americans studied in a high school in the 1930s.
Mrs. Parks also succeeded in gaining the right to vote, which was very difficult for blacks under the segregation laws( 种族隔离制度 ) . In 1943, she began working as a secretary for the NAACP----National Association for the Advancement of Colored People.
Mrs. Parks made her historic decision on December 1,1955. She recalled in her autobiography(自传) ：
“When the driver saw me still sitting, he asked if I was going to stand up and I said , ‘ No, I’m not.’ Then he said , ‘ Well , if you don’t stand up , I’m going to have to call the police and have you arrested .’ I said , ‘ You may do that.’”
Mrs. Parks died on October 24,2005. “ She sat down in order that we might stand up,” said civil rights leaders Jesse Jackson. “ Her imprisonment opened the doors for our long journey to freedom.”

Every student has tests when they are at school. But have you ever been so worried about the tests that you can’t fall asleep at night? Have you ever felt sick or had a headache during a test? 【小题1】 This worry in your mind can make your body feel bad. You may feel angry, frustrated, scared, or afraid --- which can give you a stomachache or a headache.
【小题2】 Good or normal stress might happen when you are called to answer a question in class or when you have to give a speech. This kind of stress can help you to get things better done. 【小题3】
But bad stress can happen if the stressful feelings keep going over a long time. You may not feel well if your parents are fighting, if a family member is ill, if you are having problems at school, or if you are going through anything else that makes you upset every day. 【小题4】
【小题5】 That means making good decision about how to spend your time. If you are only dealing with school stuff and have no time to play, you can get stressed. Make sure you keep your SELF in mind: Sleep, Exercise, Leisure and Food.
